摘　　要：为了探明不同沟垄覆膜连作种植对马铃薯生长特征及品质影响的差异,以当地主栽品种‘新大坪’为试验材料,研究了平畦不覆膜（CK）、平畦覆膜（T1）、全膜双垄垄播（T2）、全膜双垄沟播（T3）、半膜沟垄垄播（T4）、半膜膜侧种植（T5）6种栽培模式连作种植对马铃薯生长、产量及品质的影响。结果表明,与CK相比,沟垄和覆膜栽培能显著促进连作马铃薯生长,且T3处理促进作用最大;并能显著提高连作马铃薯产量,增产幅度为1.5%~29.8%,其中T2处理产量最高。沟垄和覆膜处理马铃薯薯块氨基酸总量和还原糖含量较CK存在显著差异,其中CK的氨基酸总量最高,T4的还原糖含量最高;而薯块干物质、蛋白质及淀粉含量差异未达到显著水平。In order to ascertain the impact of different film mulching and ridge and furrow planting incontinuous cultivation on growth, yield and quality of potato, the local cultivars‘Xindaping＇as test material,studied the effects on six cultivation modes of potato growth, yield and quality, which were harrowed beddingsystem without film mulching（CK）, harrowed bedding system with film mulching（T1）, completely mulchedalternating narrow and wide ridges with ridge planting（T2）, completely mulched alternating narrow and wideridges with furrow planting（T3）, plastic mulched raised bedding system with bedding planting（T4） and plasticmulched raised bedding system with furrow planting（T5）. The results indicated that, compared with CK, otherfive treatments with film mulching and ridge- furrow planting could all promote the growth of potato incontinuous cultivation, among which the promoting effect of T3 was the greatest, and significantly increased the yield with 1.5%- 29.8% and the yield of T2 was the highest. Moreover, compared with CK, there hadsignificantly difference on amino acid content and reducing sugar content between film mulching and ridge-furrow treatment and CK, and amino acid content in CK and reducing sugar content in T4 was the highest.However, there had no difference found on content of dry matter, starch and soluble protein of tuber in all treatments.
